Notes:
Formation of hollow structure through oxidation of Al nanoparticles was studied byapplying transmission electron microscopy. Al nanoparticles 6~8 nm in diameter were observed tobecome hollow particles after having been exposed to air at 295 K for a few minutes. An analysis ofthe Debye-Sherrer rings in the selected area diffraction patterns before and after oxidation showedthat hollow oxide nanoparticles are amorphous. The formation mechanisms of hollow oxide arediscussed based on the low-temperature oxidation mechanism of Al and on the comparison with ourprevious results of hollow ZnO formation via oxidation of Zn nanoparticles
